Vedclass · Answer

(C) Time taken to count $4$ grains of wheat = $1$ second. Number of grains in one mole = $6.022 	imes 10^{23}$. Time required in seconds = $\frac{6.022 	imes 10^{23}}{4}$ seconds. To convert seconds into years,divide by $(60 	imes 60 	imes 24 	imes 365)$. Time in years = $\frac{6.022 	imes 10^{23}}{4 	imes 60 	imes 60 	imes 24 	imes 365} \approx 4.77 	imes 10^{15} 	ext{ years}$.

If it takes $1$ second to count $4$ grains of wheat,then the time required to count one mole of wheat grains is ...... years.
